Full Text search queries

This release introduces support for Full-text search SPARQL queries, allowing users to execute approximate string matching on RDF Terms retrieved by SPARQL queries. To accomplish this integration, it follows an approach similar to BlazeGraph and defines several magic predicates that are given special meaning, and when encountered in a SPARQL query, they are interpreted as configuration parameters for a full text search query.
